3. In Vertical Position, enter the number of divisions (positive or negative) relative to the zero line of the
grid where the display begins.The top of the first trace appears at this position.
In the example above, the first Line trace (D0) starts at positive 4.0 divisions off the zero line, or at the
very top of the eight vertical division grid.
4. In Group Height, enter the total number of grid divisions the entire display should occupy. All the
selected traces (Line and Bus) will appear in this much space.
Individual traces are resized to fit the total number of divisions available. The example above shows a
group of three Line traces plus the Bus trace occupying a Group Height of 4.0 divisions. Each trace
takes up one division.
5. Check the Group box to enable the display.
To close traces, uncheck the Group box , or touch-and-hold on the Digital<#> descriptor box and
choose Off from the pop-up menu.
Renaming Digital Lines
The labels used to name each line can be changed to make the user interface more intuitive. Also, labels
can be "swapped" between lines.
Changing Labels
1. Set up the digital group.
2. Touch Label and select from:
l
Data - the default, which appends "D." to the front of each line number.
l
Address - appends "A." to the front of each line number.
l
Custom - lets you create your own labels line by line.
3. If using Custom labels:
l
Touch the Line number button below the corresponding checkbox. If necessary, use the
Left/Right Arrow buttons to switch between banks.
l
Use the virtual keyboard to enter the name, then press OK.
The button and any active line traces are renamed accordingly.
Swapping Lines
This procedure helps in cases where the physical lead number is different from the logical line number
you would like to assign to that input (e.g., a group is set up for lines 0-4, but lead 5 was accidentally
attached to the probing point). It can save time having to re-attach leads or re-configure groups.
1. Select a Label of Data or Address.
2. Touch the Line number button below the corresponding checkbox. If necessary, use the Left/Right
Arrow buttons to switch between banks.
3. From the popup, choose the line with which you want to swap labels.
The button and any active line traces are renumbered accordingly.
